It would possibly be more correct to ask on the Mojo users mailing list,
but I am subscribed to this list too.

The maven plugin uses ANTLR 3.0.1, as found over here,

  http://repo1.maven.org/maven2/org/antlr/antlr/3.0.1/

I'll try and have a look at the problem.  Would it be possible for you
to send me the actual grammar?
